I have just resumed mining on asia1.ethermine.org.
After about 40 minutes, one of my workers ( I only have 2 workers ) shows up with 1 stale share .. but the console output from ethminer from that worker does NOT show any stale share at all !!! It shows A35+0:R0:F0 ( 35 accepted, 0 stales, 0 rejects, 0 fails ).
How can that be???
